So I’ve recently ran into the Coolant Temperature High or whatever warning light. Fans kick on, water pump appears to be working properly, and as best as I can tell the thermostat is doing it’s job as well. When I first noticed the problem I checked the coolant and it was low, almost a 1 1/2 gallons. I filled it up and burped it out and in the five minutes of doing so the temp rose to 215* according to the “secret menu” (outside temp was in the low 50’s). I let it sit over night and check the coolant the next day and it seemed a little low but only just needed a slight top off. Brought it to the shop to get pressure tested and on the 10 minute or so drive the temp went back up to 200*. The shop found a slight leak at the bottom of the radiator. I’m getting a new, stock radiator, but is it worth keeping the Mishimoto and trying to find some one to repair it? Is that something that can even be done? I am also putting in a new thermostat. Is there anything else I should be worried about here?
